Maintaining the Transport Directory

Procedure

For tp, the transport directory must fulfill the following requirements (depending on the operating system):

UNIX

In a transport network, there must be a single physical transport directory that can be reached from each host with the same path.

In UNIX systems, this directory can be a soft link, pointing to the correct transport directory or mount point.

You must store the chosen path in two parameters:

  • Parameter DIR_TRANS for the SAP System in the instance profile

The default value for the transport directory is /usr/sap/trans in UNIX.

Windows

Transport groups comprised of Windows systems, or of Windows and UNIX systems are supported.

For more information on creating a heterogeneous transport group, see Transport Control under Windows.

SAP allows you to name a central transport host on the Domain Name Server that is valid for all Windows systems.

For more information on specifying a central transport host on the domain name server, see Specifying the Central Transport Host.

Each transport group must have a single physical transport directory that can be accessed by all machines.

This directory is described by the parameters:

  • transdir (transport profile)
  • DIR_TRANS (instance-specific profile)

If you have entered a transport host on the domain name server, the directory is under \\$(SAPTRANSHOST)\sapmnt\trans by default.

Otherwise it is under \\$(SAPGLOBALHOST)\sapmnt\trans .

The transport directory is described by the following parameters:

  • SAPTRANSHOST

Name of the host configured as the central transport host on the domain name server

  • SAPGLOBALHOST

Name of the host on which the central system is installed

  • sapmnt

Global share that points to the \usr\sap file tree on the central instance

Note the different naming conventions used for the parameters transdir and DIR_TRANS:

The path entered for the parameter DIR_TRANS does not end with a "\", whereas the path entered for the parameter transdir does end with a "\":

DIR_TRANS = T:

transdir = T:\

The DIR_TRANS profile parameter that you set and the parameter transdir in the transport profile must point to the same transport directory.

IBM eServer iSeries

In a transport network, there must be a single physical transport directory that can be reached from each host with the same path.

In iSeries systems, this directory can be a soft link, pointing to the correct transport directory or mount point.

You must store the chosen path in two parameters:

  • Parameter DIR_TRANS for the SAP System in the instance profile

The default value for the transport directory is /usr/sap/trans in iSeries.
